"At the end of 2010, the 'open-source' software movement, whose activists tend to be fringe academics and ponytailed computer geeks, found an unusual ally: the Russian government. Vladimir Putin signed a 20-page executive order requiring all public institutions in Russia to replace proprietary software, developed by companies like Microsoft and Adobe, with free open-source alternatives by 2015."

Please enlighten me how that "salty" network engineer would monitor even Skype traffic, for example? Of course, Skype might have nothing to do with "sensitive areas", but how is it different from any other closed source application leaking encrypted traffic into your network?

Because anything on a non-standard port or even (and depending on the port) using a non-standard protocol on a standardised port would be firewalled.

You can even go further and blacklist outgoing IPs or even whitelist "safe" IPs for outgoing connections.
